SUPPORT FfmA 'WIRES' yF11-ed oct.' 4, 1940 Qi? f Y 20 5' INVENToRPatented May 26, 1942 Charles William Roberts, Alexandria, Va.. as-

signor to American Telephone and Telegraph Company,v a corporation ofNew York Application October 4, 1940, Serial No. 359,645 4 claims. u 01.24e- 72) This invention relates to supports for electric Wire orconductor runs, and more particularly to supports of this characterwhich may be readily attached to or detached from positions.

In connection with the construction of buildings and particularlymulti-unit apartment build-v ings, considerable use is made of rolledsteel I- beam floor joists. The steel I-beams are provided with theusual flanges, and in accordance with well-known construction, concretearches extend between these anges, the springing line of each archresting on the lower flange of the beam.

It is one of the objects of this invention to provide a simple andinexpensive support which may be readily attached to or detached fromthe joists or I-beams used in constructions such as above outlined, sothat wire or conductor runs may be introduced therethrough.

Another object of the invention is to provide a support whereby the wireruns lie closely adjacent the ceiling or the like.

These and further objects will be apparent from the followingdescription when considered in connection with the accompanying drawingin which certain embodiments of the invention are illustrated.

Referring to the drawing,

Figure 1 illustrates one embodiment of the improved support. j

Fig. 2 shows another embodiment thereof.

Fig. 3 is a sectional View of an I-beam and associated concrete workincluding an arch showing the improved support attached to a iiange ofthe I-beam Vand with the Wire runs extending through the support in adirection perpendicular to the I-beam.

Fig. 4 is a View similar to Fig. 3 but having the bridle ring portion ofthe support turned so that the wire runs lie in a position parallel tothe I- beam, and

Fig. 5 is a sectional view showing a series of I-beams and associatedarches with bridle ring portions of certain of the supports lying in aposition so that the wire runs extend in a direction perpendicular tothe I-beams, the bridle ring portion of a terminating support beingturned so that the wire runs extend in a parallel direction to theI-beams.

In the drawing I-beams 5 which provide floor joists are shown as lyingin concrete formed into arches 6 extending between the I-beams. Thelower edges of the flanges of the I-beams extend beyondr theconcrete, orthe concrete may be removed therefrom to provide portions to which theimproved support may be attached. The support includes a threaded'elongated shank member 1. This shank member is of suiicient length toextend beyond the edges of an I-beam. One end of the shank member isbent to form a bridle ring portion 8. This ring may be so arranged withrespect to the shank member that the axis of said ring lies in parallelrelation to the shank when it is desired to have the Wire or conductorruns extend in the direction shown in Fig. 3 of the drawing. When it isdesired to have the wire or conductor runs 9 extend in the directionindicated in Fig. 4, the bridle ring 8 is turned so that its axis liesin a perpendicular relation to its shank. The wire or conductor runs, ofcourse, may be extended in other angular directions than those justreferred to by bending the bridle ring at a desired angle.

A pair of clips or brackets l0, I0 are movably mounted on the shankmember 1 in oppositely positioned relation to each other. These clips orbrackets are adapted to clamp and firmly grip the exposed edges of thebottom flange of the I-beam 5 and hold the improved support securelythereon. In Fig. 1 these flange-engaging members are shown as having asubstantially arcuate formation, the upper portions extending furtherfrom the opening through which the shank member passes than the lowerportions to provide a maximum engaging area. In Fig. 2 theflangeengaging members l0, I0 are shown as of substantially rectangularformation and have upper portions ll of triangular shape which extendtherefrom. These portions are adapted to pass over the ange edges, asindicated in Fig. 4 of the drawing. Lock nuts l2 are provided on theshank at each side of the flange-engaging members I0, l0 to bind andhold them against the edges of the flanges when the members lil, l0 areadjusted in desired positions.

It will be apparent from the above description that the improved supportis attached to carry Wire or conductor runs closely adjacentV a ceiling.

While the arrangements of this invention have been illustrated as'embodied in certain specific forms which have been deemed desirable, itwill be understood that they are capable of embodiment in many andwidely varied forms Without departing from the spirit of the inventionas defined in the appended claims.

What is claimed is:

1. A support for wires and cables including a threaded elongated shankmember, oppositely positioned clamping members movable thereon, and

a ring memberintegral with andcarried on one 3. A support adapted to beattached to I-beams n and the like to hold Wire runs closely adjacent aceiling, said support having a threaded elongated shank member, a ringmember on one end of the shank member and integral therewith throughwhich the wire runs pass, and 'clamping means` engaging a flange of theI-beam to lock the support thereto.

4. A support adapted to be attached to I-beams to hold wire runs closelyadjacent a ceiling, said support having a threaded elongated shankmember, a bridle ring positioned at one end of the shankmember andintegral therewith through which wire runs pass, said bridle ring beingadapted to be turned with respect to the shank member to carry wire runsin a direction parallel to the I-beams and also perpendicular thereto,clamping means carried by the shank for engaging a ange of the I-beam,and locking means for holding the vclamping means in position.
